The E is widely available in the UK - yet it is more than twice the equivalent U.S. price - £110 versus $70 dollars for the same 16Gb version... the E was even more expensive than the A was when I got mine, so it is hard for me to recommend the E to anyone in the UK. I really don't get the pricing policy.

The S is widely available and around the same price as the E, but it's a much better player, playlists, tru-black screen, SenseMe, 50hrs battery and almost all metal.

I love mine - I got it for £52 unused - it's definitely the best DAP I've ever tried in terms of features and I use it pretty much every day.
